RUNNING-GEAR FOR CI-IILDRENS CARRIAGES AND THE LIKE.

Specification of Letters Patent.

Patented May 11, 1920.

Application filed August 22, 1919. Serial No. 319,237.

To all whom it may concern:

Be it known that I, CHARLES A. LIND- BERG, a citizen of the UnitedStates, residing at Sturgis, county of St. Joseph, State of Michigan,have invented certain new and useful Improvements in Running-Gears forChildrens Carriages and the like, of which the following is aspecification.

This invention relates to improvements in a running gear for childrenscarriages and the like.

The main objects of this invention are:

First, to provide an improved running gear the parts of which may beeconomically produced and assembled and at the same time provide a veryrigid structure.

Second: to provide an improved running gear which is comparatively lightand at the same time very strong.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I is a side elevation of a structure embodying the features of myinvention, the wheels being omitted and the body being shownconventionally and partially broken away.

My improved running gear frame comprises the rear axle 2, front axle 3and side members 1. The side members are preferably formed of tubing.The axles illustrated are formed from sheets or bars the particularconstruction, however, forming no part of this invention. The rear axle2 is secured to the side members by meansof coupling members 5,cruciform in general shape, disposed between the axle and the sidemembers, with one of their arms parallel with the axle and the other armparallel with the side members. The arms 6 of the coupling member areprovided with coupling lugs 7 each of which is clampedupon the axle, thecoupling members being stampings so that bendable integral arms areprovided. The coupling members are further secured to the axle by meansof centrally disposed rivets 8. The coupling mem bers are secured to theside members by means of clamping lugs 9 and 10 at the ends of thecoupling member arms 11. The lugs 9 are clamped about the side memberswhile the lugs 10 are extended above the side members to engage thesprings 12.

These springs 12 are provided with clips 13 secured on their undersides, while the side members have recesses 14: therein, adapted toreceive these clips. Bolts 15 are disposed through the clips and clampthe lugs 10 up in the springs as shown in Figs. V, VI and VII. The partsare thus rigidly secured together without the aid of braces or crosspieces and with few bolts and rivets. y

The rivet 8 prevents movement of the coupling member longitudinally ofthe axle, while the clips engaging the recesses of said members preventmovement of the coupling member longitudinally of the side members. Thusthe single 'pair of stampings with the bolts and rivets described securethe axles and side members and rear springs.

The front ends of the side members are flattened and downwardly offsetat 16 and conformed to engage the front axle, being secured thereto bythe bolts or rivets 17. The front springs 18 are secured to the sidemembers by means of the clips 19, having downwardly projecting ears 20engaging the.

side members and upwardly projecting'ears 21 engaging the springs. Thebolts 19 through the clips effectively secure the springs.

The springs 12 andl are connected by spring members 22 carrying acentral cross piece 23. On the under side of the body are brackets 24connected by the cross piece 25 which is pivoted to the cross piece 23at 26 so that the body may be reversed. A latch 27 is mounted at 28 onthe cross piece 29 connecting the spring members 22. The latch isprovided with a keeper 30 adapted to engage the cross pieces 23 and 25when they are brought into alinement. The latch 27 extends rearwardlyunder the rear cross piece 29 which carries a supporting loop 31therefor.

The handle 88 is secured to the side pieces a by means of the clips 34embracing both the handle and the side pieces and secured thereon by theclamping bolts This permits the handle being removed for packing,thereby very materially reducing the size of the package, the cost ofpacking and transportation.

The structure is such that the retailer or user can readily assemble thesame. The wheels are preferably detachably secured by means described inthe application for Letters Patent filed concurrently herewith.

I have illustrated and described my improvements in a form in which Ihave embodied them in practice. I have not attempted to illustrate ordescribe certain modifications or adaptations which I contemplate as Ibelieve the disclosure made will enable those skilled in the art towhich my invention relates to embody or adapt the same as may bedesired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a running gear, the combination of side members, a rear axledisposed below said side members, springs disposed above said sidemembers having clips on their under sides, said side members havingindentations to receive said clips, cruciform coupling members disposedbetween the axle and side members with their transverse arms parallelwith the axle and provided with clamping lugs engaging the axle andtheir longitudinal arms parallel with said side members and providedwith clamping lugs at their ends embracing the same, forward side memberclamping lugs betudinal arms parallel with said side members andprovided with clamping lugs at their ends embracing the same, forwardside member clamping lugs being extended above the side members toengage said springs, and clamping bolts arranged through said clampinglugs.

3. In a running gear, the combination of e a side member, an axle, aspring having a clip thereon, said side member having a re cess adaptedto receive said clip, a cruciform coupling member dlsposed between the"axle and side member, one arm of said cou pling having clamping lugs atits ends engaging the axle, the other arm being provided with clampinglugs at its ends engaging the side member, one pair of which lugs areextended to engage said spring, and a clamping bolt arranged throughsuch clampmg lugs to engage sa1d spring clip,

said coupling member being further secured to said axle by a rivetdisposed centrally through the coupling member.

l. In a running gear, the combination of a side member, an axle, aspring, a coupling member disposed between said axle and side member andprovided with lugs engaging both coupling member and side members, saidcoupling member being a stamping and said lugs bendable and clamped uponthe parts, one pair of said lugs being extended to engage said spring,and a clamping bolt for such pair of lugs.

5. In a running gear, the combination of a side member, an axle, and acoupling member disposed between said axle and side member and providedwith integral lugs engaging both coupling member and side member, saidcoupling member being a stamping and said lugs bendable and clamped uponthe parts.

6. In a running gear, the combination of a pair of side members, a rearaxle disposed below said side members, cruciform coupling membersdisposed between said axle and side members with their transverse armsparallel to the axle and provided with clamping lugs at their endsengaging the axle and with their longitudinal arms parallel With saidside members and pro- In Witness whereof, I have hereunto set vided withclamping lugs at their ends emmy hand and seal in the presence of twobracing the same, said coupling members vvltnesses.
